The board get a better planing, better angle up wind and downwind. The biggest step is downwind, the board doesn't heat the water and glide a lot, so we increase the avantage of the F161 up wind and win a lot downwind.

As I understand you (Remi) have done most R&D on the new Apollo and on the new F162 as well?
Question:If in competition slalom is done from 15 knots and up and formula will only be done in winds form 8 knots upto 15 knots, how close will the Apollo be on the tail of the F162, performance-wise??

Please take in account to compare both boards in their maximum set up within formula rules. Has the medium and stronger wind performance of the Apollo been so much upgraded that the new Apollo may be a racing option in 8- 15 knots conditions?

The Apollo is a high performance plaining board, you can plane under 8 knots with the 75cm fin and minimum 11mē. In your configuration I will choose the F162 who is slight faster on Formula rules but with 75cm I will choose the Apollo.
